well... im already lvl 40... but i still dont know how to finish the dungeon in the lot left corner
of the korin village map...
you may call it the RP casle dungeon.
any way i constantly reach the middle of the dungeon and then faceing a door! i cant blow it up\ talk to it\open it nothing!!!
what do i do?!

thenx for the helpers :)

Do you have a screenshot? I may know what you're talking about.. you need oil I think.

You need an item to open it. It looks like a glass of milk.

where can i find this item?

a npc give it to u by accepting a quest in the dungeon.
